inline

Compute quasi-normal step by minimizing the norm of the linearized constraint.

Compute an approximate solution of the problem

\[ \begin{array}{rl} \min_{n} & \|c'(x_k)n + c(x_k)\|^2_{\mathcal{X}} \\ \mbox{subject to} & \|n\|_{\mathcal{X}} \le \delta \end{array} \]

The approximate solution is computed using Powell's dogleg method. The dogleg path is computed using the Cauchy point and a full Newton step. The path's intersection with the trust-region constraint gives the quasi-normal step.

Parameters

[out]	n	is the quasi-normal step; an optimization-space vector
[in]	c	is the value of equality constraints; a constraint-space vector
[in]	x	is the current iterate; an optimization-space vector
[in]	delta	is the trust-region radius for the quasi-normal step
[in]	con	is the equality constraint object
